osdep: Undefine FSCALE definition to fix Solaris builds
Solaris defines FSCALE in <sys/param.h>:
301 /*
302 * Scale factor for scaled integers used to count
303 * %cpu time and load averages.
304 */
305 #define FSHIFT 8 /* bits to right of fixed binary point */
306 #define FSCALE (1<<FSHIFT)
When emulating the SVE FSCALE instruction, we defines the same name
in decodetree format in target/arm/tcg/sve.decode:
1129:FSCALE 01100101 .. 00 1001 100 ... ..... ..... @rdn_pg_rm
This leads to a definition clash:

Log Message:
-----------
vhost: Always initialize cached vring data
vhost_virtqueue_start() can exit early if the descriptor ring address is
0, assuming the virtqueue isn’t ready to start.
In this case, all cached vring information (size, physical address,
pointer) is left as-is. This is OK at first startup, when that info is
still initialized to 0, but after a reset, it will retain old (outdated)
information.
vhost_virtqueue_start() must make sure these values are (re-)set
properly before exiting.
(When using an IOMMU, these outdated values can stall the device:
vhost_dev_start() deliberately produces an IOMMU miss event for each
used vring. If used_phys contains an outdated value, the resulting
lookup may fail, forcing the device to be stopped.)

Fix const qualifier build errors with recent glibc
A recent change in glibc 2.42.9000 [1] changes the return type of
strstr() and other string functions to be 'const char *' when the
input is a 'const char *'.
This breaks the build in various files with errors such as :
error: initialization discards 'const' qualifier from pointer target type
[-Werror=discarded-qualifiers]
208 | char *pidstr = strstr(filename, "%");
| ^~~~~~
Fix this by changing the type of the variables that store the result
of these functions to 'const char *'.
