linuxloader.bbclass: add musl libc support

Browse Source 
Current linuxloader.bbclass does not support musl libc ldso, so add it
in.

After changing, now the linuxloader function will call a subfunction
according to which virtual/libc is being used, glibc or musl, the
linuxloader_musl function is made on top of the LDSO macro defined
in musl source, by mapping related OE variables to it.

Change tested on following machines:
"genericx86"
"genericx86-64"
"beaglebone"
"qemumips64"
"qemuarm64"
"mpc8315e-rdb"
"edgerouter"
"qemumips"
"kc705-microblazeel" - meta-xilinx
"qemuppc"
